3775276050 Update minimum Rust version in CI to 1.43.0. 
Firefox currently requires vendored Rust code (including Cranelift) to
compile on Rust 1.43.0, according to this line:

https://searchfox.org/mozilla-central/rev/eb9d5c97927aea75f0c8e38bbc5b5d288099e687/python/mozboot/mozboot/util.py#16

Whenever that version is updated, we can bump this CI check's Rust
version accordingly.

a1bdf11602 machinst x64: fix gen_store_base_offset for multi-value returns; 
The previous method assumed that this could be used only for I64 values,
but this is actually used for multi-value returns, which can have any
type.

b4a2dd37a4 machinst x64: rename input_to_reg to put_input_to_reg; 
Eventually, we should be able to unify this function's implementation
with the aarch64 one; but the latter does much more, and this would
require abstractions brought up in another pending PR#2142.

x64 new backend: port ABI implementation to shared infrastructure with AArch64.

e8f772c1ac x64 new backend: port ABI implementation to shared infrastructure with AArch64. 
Previously, in #2128, we factored out a common "vanilla 64-bit ABI"
implementation from the AArch64 ABI code, with the idea that this should
be largely compatible with x64. This PR alters the new x64 backend to
make use of the shared infrastructure, removing the duplication that
existed previously. The generated code is nearly (not exactly) the same;
the only difference relates to how the clobber-save region is padded in
the prologue.

This also changes some register allocations in the aarch64 code because
call support in the shared ABI infra now passes a temp vreg in, rather
than requiring use of a fixed, non-allocable temp; tests have been
updated, and the runtime behavior is unchanged.

38428e1fbb Expand modules instantiated in instantiate-wasm-smith 
This commit uses the new `MaybeInvalidModule` type in `wasm-smith` to
try to explore more points in the fuzz target space in the
`instantiate-maybe-invalid` fuzz target. The goal here is to use the raw
fuzz input as the body of a function to stress the validator/decoder a
bit more, and try to get inputs we might not otherwise generate.

e92f949663 AArch64: Introduce an enum for ternary integer operations 
This commit performs a small cleanup in the AArch64 backend - after
the MAdd and MSub variants have been extracted, the ALUOp enum is
used purely for binary integer operations.

Also, Inst::Mov has been renamed to Inst::Mov64 for consistency.
